Blake Griffin -- Ripped Clip (PHOTO)

Blake Griffin showed off his insane physique as he played around in the ocean in Hawaii with his son Ford and baby mama Brynn Cameron.

FYI ... Blake and Cameron broke up a long time ago, but they seem to do these annual vacations for the kid.

The Los Angeles Clippers star hasn't been seen out with his son often ... though he did bring him to a post-game press conference following the team's big win over the San Antonio Spurs in Game 7 of their first round series.

Griffin and Cameron have had an on-again/off-again relationship over the years. Cameron famously has another kid ... with former NFL and USC quarterback Matt Leinart.
